Hankook tire pressure
I just bought new 275/70R22.5 AH12 hankook tires for my MH and cannot the weight to pressure chart anywhere. Hopefully somebody has been able to track the down and would help me out so I could get the correct pressure in them. All help appreciated and thank you in advance.

If no weight/pressure chart is available then you should run the minimum pressure for the maximum weight rating of the tire as molded into the sidewall.

I've attached the Catalog for their commercial tires that will include the AH12. The inflation tables are on the last page. Your size is listed on the chart on the right side of the page titled "Tubeless."

hankook tires
I finally called the company to find out what pressure to run in my tires. The gentleman said to go by what the coach sticker said. Mine said to run at 85psi, so that is what I do.

A much better thing to do is weigh you rig & than go by the chart for the tires & weight you have.

Try this. It's all the way at the end of the document.

I think you will find that the Goodyear, Bridgestone charts match the Hankook charts.
Michelin is only company to my knowledge that has slightly different numbers. But even there they are +/- 5 psi from the GY and BS charts.

I'm seriously considering the Hankook tires. However, I looked at the chart and didn't see the 295/80/22.5 listed. Did I miss something?

I may have figured it out, but not certain.. I think I look at the 11R22.5 line item in the chart.

 That is correct. You will not find any tire mfgr. that recommends inflating to less air pressure than the federally-mandated tire placard.

Correct because the inflation shown on the placard is the inflation needed for the tires to support the GAWR.
Issue is that not everyone is at the GAWR some are significantly below.
